[Gluster-users] WORM seems to be broken.

[Paul Guo]

Here are the steps to reproduce this issue. (gluster version 3.5.2)


On one server lab1 (There is another server lab2 for replica 2):


[root at lab1 ~]# gluster volume set g1 worm on
volume set: success
[root at lab1 ~]# gluster volume stop g1
Stopping volume will make its data inaccessible. Do you want to continue? (y/n) y
volume stop: g1: success
[root at lab1 ~]# gluster volume start g1
volume start: g1: success
[root at lab1 ~]# gluster volume info
 
Volume Name: g1
Type: Distributed-Replicate
Volume ID: fbd79e82-b079-4d19-ae5a-b4279c31bac3
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: lab1:/brick1
Brick2: lab2:/brick1
Brick3: lab1:/brick2
Brick4: lab2:/brick2
Options Reconfigured:
diagnostics.brick-log-level: TRACE
features.worm: on


On client (also be one of the servers lab1):
[root at lab1 g1]# mount -t glusterfs -o worm lab1:g1 /mnt

process info of the gluster mount process.
root      2851     1  0 21:28 ?        00:00:01 /usr/sbin/glusterfs --worm --volfile-server=lab1 --volfile-id=g1 /mnt



Here is the log of the client.

~                                                                    


It looks like it fails to lock the directory (?) becuase WORM calls ro_entrylk() which is originally for the read-only feature of the file system.
